re: #6 Locker
I don’t think it’s about “religious display in public” but more “religious display on public land/property” which I think should be completely free of all this crap. It’s a public park, not a billboard for your favorite voodoo sect or lack thereof.
If a public place is designated for free speech displays, then religious groups have equal access for their speech - as long as the same rules (city permits, for instance) apply to everyone. Religious folks don’t lose their free speech rights just because they are on public property.
